DPDK Release 23.07
==================

New Features
------------

* **Added AMD CDX bus support.**

  CDX bus driver has been added to support the AMD CDX bus
  which operates on FPGA based CDX devices.
  The CDX devices are memory mapped on system buses for embedded CPUs.

* **Added MMIO read and write API to PCI bus.**

  Introduced ``rte_pci_mmio_read()`` and ``rte_pci_mmio_write()`` APIs
  to PCI bus so that PCI drivers can access PCI memory resources
  when they are not mapped to process address spaces.

* **Added ethdev Rx/Tx queue ID check API.**

  Added ethdev Rx/Tx queue ID check API.
  If the queue has been set up it is considered valid.

* **Added LLRS FEC mode in ethdev.**

  Added LLRS algorithm to Forward Error Correction (FEC) modes.

* **Added flow matching of Tx queue.**

  Added ``RTE_FLOW_ITEM_TYPE_TX_QUEUE`` rte_flow pattern
  to match the Tx queue of the sent packet.

* **Added flow matching of Infiniband BTH.**

  Added ``RTE_FLOW_ITEM_TYPE_IB_BTH`` to match Infiniband BTH fields.

* **Added actions to push or remove IPv6 extension.**

  Added ``RTE_FLOW_ACTION_TYPE_IPV6_EXT_PUSH`` and ``RTE_FLOW_ACTION_TYPE_IPV6_EXT_PUSH``
  to push or remove the specific IPv6 extension into or from the packets.
  Push always puts the new extension as the last one due to the next header awareness.

* **Added indirect list flow action.**

  Added API to manage (create, destroy, update) a list of indirect actions.

* **Added flow rule update.**

  * Added API for updating the action list in an already existing rule.
    Introduced both ``rte_flow_actions_update()`` and
    ``rte_flow_async_actions_update()`` functions.

* **Added vhost callback API for interrupt handling.**

  Introduced a new callback, ``guest_notify`` that can be used to handle
  the interrupt kick outside of the datapath fast path.
  In addition, a new API, ``rte_vhost_notify_guest()``,
  was added to raise the interrupt outside of the fast path.

* **Added vhost API to set maximum queue pairs supported.**

  Introduced ``rte_vhost_driver_set_max_queue_num()`` to be able to limit
  the maximum number of supported queue pairs, required for VDUSE support.

* **Added VDUSE support into vhost library.**

  VDUSE aims at implementing vDPA devices in userspace.
  It can be used as an alternative to Vhost-user when using Vhost-vDPA,
  but it also enables providing a virtio-net netdev to the host
  when using Virtio-vDPA driver.

  A limitation in this release is the lack of reconnection support.
  While VDUSE support is already available in the upstream kernel,
  a couple of patches are required to support network device types,
  which are being upstreamed:
  https://lore.kernel.org/all/20230419134329.346825-1-maxime.coquelin@redhat.com/

    current FEC mode from a device.
  * Added partial support for transfer flow actions ``SET_IPV4_DST``, ``SET_TP_DST``,
    ``SET_IPV4_SRC`` and ``SET_TP_SRC`` on SN1000 SmartNICs.
  * Added support for transfer flow action ``INDIRECT`` with subtype ``COUNT``,
    for aggregated statistics.

  for uniform passthrough (UPT). The patches also add support
  for new capability registers, large passthrough BAR and some
  performance enhancements for UPT.

* **Added new algorithms to cryptodev.**

  * Added asymmetric algorithm ShangMi 2 (SM2) along with prime field curve support.
  * Added symmetric hash algorithm SM3-HMAC.
  * Added symmetric cipher algorithm ShangMi 4 (SM4) in CFB and OFB modes.

  The library supports all PDCP algorithms
  and leverages lookaside crypto offloads to cryptodevs for crypto processing.
  PDCP features such as IV generation, sequence number handling, etc are supported.
  It is planned to add more features such as packet caching in future releases.

  See :doc:`../prog_guide/pdcp_lib` for more information.

    to choose RTC or mcore dispatch model.

* **Added DMA device performance test application.**

  Added an application to test the performance of DMA device and CPU.

  See the :doc:`../tools/dmaperf` for more details.


Removed Items
-------------

* Removed LiquidIO ethdev driver located at ``drivers/net/liquidio/``.


API Changes
-----------

* ethdev: Ensured all entries in MAC address list are unique.
  When setting a default MAC address with the function
  ``rte_eth_dev_default_mac_addr_set``,
  the default one needs to be removed by the user
  if it was already in the address list.


ABI Changes
-----------

* No ABI change that would break compatibility with 22.11.

* ethdev: In the experimental ``struct rte_flow_action_modify_data``:

  * ``level`` field was reduced to 8 bits.
  * ``tag_index`` field replaced ``level`` field in representing tag array for
    ``RTE_FLOW_FIELD_TAG`` type.


Known Issues
------------

* **Testpmd is not forwarding on queues individually stopped.**

  Testpmd forwards packets on started queues.
  If a queue explicitly stopped, and later port stopped and started again,
  the status of the previously stopped queue is not updated,
  so forwarding is not working on those queues.

  As a workaround start queues back explicitly, instead of port stop/start.
